-DY-EING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 354,281, dated December 14, 1886.

I Applicati n filed September 15,1886. Serial No, 213,566. (No model.)

To aZZ whom it may concern.-

Be it known that I, LEONARD WELDoN, of Amsterdam, in the county of Montgomery, in the State of N ewYork, have invented new and useful Improvements in Dyeing Apparatus, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of dyeing apparatus designed for dyeing textile fabrics, and in which a rotary wheel or cylinder is arranged in the dye-vat to intermittently dip the articles to be dyed into the dye-liquor; and the invention consists in an improved construction and combination of the component parts of the dyeing apparatus, as hereinafter fully described, and specifically set forth in the claims, whereby the efficiency of the dyeing apparatus is materially improved.

In the annexed drawings, Figure 1 is an end elevation of my improved dyeing apparatus. Fig. 2 is a front elevation of the same. Fig. 3 is a transverse section, and Fig. 4 is a longitudinal section on line ac a", Fig. 3.

Similar letters of reference indicate corresponding parts.

A represents the dye-vat, which is of rectangular or other suitable shape and watertight, and C denotes the wheel or cylinder for dipping the articles to be dyed in the dyeliquor contained in the aforesaid vat, said cylinder being journaled at opposite ends in suitable boxes or bearings secured to the top of each end of the vat, and to one end of the shaft of the cylinder, at the exterior of the vat, is secured a worm-gear wheel, B, which meshes in a worm, D, journaled on the exterior of the vat, and a pulley, 1?, fastened to the shaft of the worm D and connected by a driving-belt with asuitable motor, serves to transmit rotary motion to the cylinder 0. I do not, however, limit myself to the aforesaid means for transmitting motion to the cylinder, as it is obvious that the same can be effected by other wellknown devices. 1

In order to dispense with unnecessary room for dye-liquor in the vat and. to economize in the use of said liquor, I form the interior of the 'vatAwith a segmental solid false bottom, F, extending from the top of one side of the vat to the center of the bottom proper thereof,

and with a segmental perforated false bottom,

F, extending from the top of the opposite side of the vat to the center of the bottom F constitutes a receptacle for the dye-liquor, which is introduced through the top of the vat and passes through the perforated bottom F into the receptacle H. A gate, I, of any suit-able and well-known form, is connected with the receptacle H to draw oh the dyeliquor when desired.

A represents a steam -pipe, which is extended into the receptacle H to heat the dyeliquor to the requisite temperature.

The cylinder 0, I form of two stout heads, bb, preferably each composed of two thicknesses or layers of wood, with the grain of one layer running crosswise the grain of the other layer, so as to prevent the warping of the heads, said heads being secured to a wooden roller, 0,

through which the shaft (1 of the cylinder is extended, and to which it is fastened. Lengthwise the interior of the cylinder 0 are extended a series of buckets, L L, which are secured at their ends to the inner sides of the heads b I). These buckets are formed either V-shaped or similar angular shape in cross-section, and are arranged adjacent to the periphery of the cylinder, and preferably in such positions as to make one side, 0, of each bucket form a longitudinal section of the exterior of the cylinder, said side of the bucket being solid, while the other side, e, of the bucket is perforated,or composed of slats placed short distances apart. From the inner edge of each bucket L toward the center of the cylinder is extended a slatted or perforated partition, n, and near the aforesaid edge of each bucket is hinged at one edge a gate, f, which has its free edge extended toward the back of the adjacent bucket.

In the operation of the described dyeing ap paratus the fabric or articles to be dyed are thrown into the buckets L L from the top of one side of the vat, and by the rotation of the cylinder Csaid articles are carried in the buckets through the dye-liquor in the vat, and are thus intermittently dipped or immersed there in. The angular or V shape of the buckets causes the articles tobe retained in the buckets after leaving the bath of dye-liquor with out moving from the positions in which they were taken up until the buckets are elevated to a position past a vertical line over the axis of the cylinder 0, when the aforesaid articles fall by gravity out of the elevated bucket and onto the back of the perforated side of the subjacent bucket and partition n, and during this fall the articles to be dyed are turned over, so that in their succeeding passage through the dye-liquor and toward the top of the cylinder the dye-liquor penetrates the layers of fabric in the buckets in opposite direction from which it passed through thesame during the previ- V ous revolution of the cylinder, and thus the fabric is dyed more uniformly throughout. Hereto'fore the buckets of the wheel or cylinder have been formed concave or rounded transversely, and this form of the buckets caused the articles in process of dyeing to be rolled over in the bucket, and thus become more or less entangled or knotted in a mass and dyed unevenly. This, it will be observed, is effectually obviated by the angular or V shape of the buckets L L of my improved apparatus.

The delivery of the dyed articles from the dyeing apparatusl make automatic by turning the hinged or pivoted gates ff so as to stand with their free edge toward the hip or ridge of the back of the adjacent bucket, as represented by the dotted lines in Fig. 3 of the drawings, said gates then serving as chutes,

upon which the dyed articles drop from the elevated buckets, and then slide out over the side of the vat.

Having described my invention, what I claim is 1. In a dyeing apparatus, the combination, with the rotary wheel or cylinder, of buckets formed angular in cross-section, as and for the purpose specified.

2. In a dyeing apparatus, the combination, with the rotary wheel or cylinder, of buckets in said cylinder adjacent to the periphery thereof, and of angular form in cross-section, substantially as shown and set forth.

3. In a dyeing apparatus, the combination,

with the rotary wheel or cylinder, of buckets of angular form in crosssection and adjacent of the exterior of the cylinder, substantially as described and shown.

5. In combination with the dye-vat and rotary cylinder, buckets in said cylinder and gates extended from the inner portion of the buckets toward the backs of the subjacent buckets,and adapted to be set inclining toward the exterior of the cylinder, substantially as and for the purpose set. forth.

6. In combination with the dyevat and rotary cylinder, buckets in said cylinder and gates, each pivoted at one edge near the inner edge of one of the buckets and having its free edge toward the back of the adjacent bucket, substantially as described and shown, for the purpose specified.

7. In combination with the cylinder 0, the dye-vat having a segmental solid false bot tom extending from the top of one side of the vat to the center of the bottom proper thereof, and a segmental perforated false bottom extending from the top of the opposite side of the vat to the center of the bottom proper thereof, and a dye liquor receptacle back of said perforated bottom, substantially as de scribed and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Amsterdam, in the county of Montgomery, in the State of New .York, this 11th day of September, 1886.
